You're talking about current Erlang releases, right?  How does that
work with module reloading?  E.g., if foo:bar/0 returns a constant
complex data structure and the result is not copied into the calling
process's private heap, what happens when a module is purged while a
process is still holding onto a reference to the data structure?
